It's not uncommon to smell alcohol in people's breath on BART, especially in the late afternoons as people are coming home from happy hour or whatver.
This morning, however, at 8:15am, I sat next to a passenger, a professional, clean-cut looking middle aged man with a suit, tie and high-end briefcase, smelling like he just spent over $200 in a bar. I didn't even need to try to smell the alcochol. The drunken scent was all over. I felt like I was in a return flight from Las Vegas.
